jacobsson Posted September 29, 2014 Share Posted September 29, 2014 Setup: - MBPr late 2013, 13", 8GB, i5- MSI GTX 970 Gaming- be quiet! System Power 7 - 500W PSU- AKiTiO Thunder2 (without its PSU, only powered by the riser)- molex powered riserPower consumption (combination of GPU, ATX PSU, AKiTiO [without PSU], riser):Idle ~ 21WValley ~ 150-160W (max. 180W)3dMark11 ~ 200W (max 215W)3dMark13_Sky ~ 195-200W (crashes after entering the cave)3dMark13_Fire ~ 170-200W (max. 210W)Furmark ~ 215W (max. 220W [100% power target])Furmark ~ 225W (max. 230W [105% power target])Furmark ~ 240W (max. 240W [110% power target])Waaaat, it crashes for you too, can you explain how it crashed for you? This means that our cards are probably fine and this is most likely a driver issue. Funny how we see +210W on a card speculated to TDP @146W? =)EDIT: And you just answered my 'does it power with riser + no Akitio PSU' -question, thanks again!

Power consumtion dropped -> no GPU use anymore.Seems like a bug to me. 3dMark or Nvidia... no idea. All the other benchmarks worked flawless.Funny how we see +210W on a card speculated to TDP @146W? =)A german hardware page (tomshardware.de) made an awesome review about "board partner" GPU layouts.Like my MSI GTX 970 Gaming, most of the cards are overclocked and used beyond the official TDP. But with more horsepower comes an exponential increasing power comsumtion. The "sweetspot" is the official TDP. Quote Link to comment Share on other sites More sharing options...

Even my PSU is turned off due to something strange happening from the GPU.I might consider clocking down to that sweet spot if necessary (since I will only use the limit of my DA-2), I really like the card so far!Thank you for helping me with the power measurements.

Slovedon Posted September 29, 2014 Share Posted September 29, 2014 It looks like my issues with not detecting my eGPU are either related to my Akitio enclosure or my Thunderbolt connection, since nothing is detected in device manager with just the Akitio plugged in (hotplugged at any stage, turned on in different orders, etc.). I'll be testing the laptop with a Thunderbolt display and the Akitio with a friends Macbook. I never use Macs, so what is the easiest way to test if the Akitio is working in OS X?

Open ; About this Mac ; More Info ; System report ; ThunderboltHere you should find the AKiTiO!This worked and the Akitio connected. On the other hand, my laptop would not connect to the Thunderbolt display, so there is some issue on my laptop's end with Thunderbolt. I'm not sure where I'll go from here... the only thing I can think of is some sort of driver (or god forbid, hardware) issue with Thunderbolt, but I know others with the G46 had no problem with this. Then again, I've only seen the Thundertek enclosure used with this machine, so perhaps there's some sort of incompatibility there. Ideas on how to troubleshoot from here, anyone?

aqqua Posted September 30, 2014 Share Posted September 30, 2014 Mbpr 13" late 2013 so far no optimus under win8.1 efi with akitio. Whatever I do there is some sort of problem. I also erased nvidia drivers with drive sweeper to install the gpu again. This time the card is not detected at all. I connected the card with pe4l v. 2.1 and it is detected I installed nvidia drivers and optimus works fine. I then connected the card with akito and the card is again not detected. Internal screen is black windows works but no signal to the external screen. Before external screen was working with akitio. any ideas about that? <strike>I think there are problems with akitio especially with optimus. So who consider playing games on internal screen should be careful before buying it.</strike> Quote Link to comment Share on other sites More sharing options...
Dschijn Posted September 30, 2014 Share Posted September 30, 2014 I will test Optimus in 2h with my setup (13" late 2013, AKiTiO and GTX 970). Quote Link to comment Share on other sites More sharing options...
aqqua Posted September 30, 2014 Share Posted September 30, 2014 @Dschijn That would be great! I was about to build your setup with gtx 970 but could't get optimus working. So I am about to send akitio back if I can't get it working. the problem might be because of lack of (something like sw2 switch on pe4l). Pe4l detects the card only with the configuration below. Otherwise it gives the same errors like akitio by restarting mac on and on. I power on pe4l, tb cable plugged in than I start mac with alt pressed to come booth option. Pe4l switches after about 15 seconds with the sw2 switch (the red light goes and it turns green) after that I boot in windows the gpu fans spins very fast and than gets slower (this means the gpu is working) I think we need that kind of configuration with akitio. I tried starting the psu but not akito adapter and I plugged in akitio when waiting in boot options like in pe4l but didn't work. (using akitio with its own adapter) The difference with pe4l is when I start psu gpu fans started spinning normal and after a while when pe4l do the switch it starts spinning faster. In akitio when I start psu without akitio gpu fans don't spin. That is the biggest difference that might prevent optimus. I would appreciate if there are any ideas about that.

euqlaog Posted September 30, 2014 Share Posted September 30, 2014 @aqqua1) Check that you have Boot Camp drivers 5.1.5640 installed (Boot Camp Support Software 5.1.5640) and the latest Nvidia drivers2) Confirm that "Turn on fast startup" is unchecked: Boot Camp: Thunderbolt devices not recognized after Windows 8 upgradeThen try the following:3) Confirm that internal screen is set as default display (external screen extended or internal only in use, try both)4) Shut down your system completely, and power on ATX PSU + AKiTiO at the same time from the power strip switch5) Alt/option key down, select windows partition quickly or wait for 5-10 seconds and then select6) If the steps 3-5 don't make it work, the final attempt is to plug in TB cable a few seconds after restartSome graphics cards require those previous 3-6 steps before internal screen can be detected. The chosen card vendor/model is one important factor if you want Optimus to be more like plug and play (I recommend EVGA). AKiTiO does support Optimus very well after you have found the right method for detection.I updated to GeForce 344.11 driver with my setup (MBPr 15" Iris Pro + EVGA GTX 780), external screen went black during the installation, but after restart Optimus worked and everything was ok. Once internal screen is detected, you need one additional shut down + restart in order to have correct resolution and icon sizes in your internal screen/external screen.

Does it work with both screens (external extended)? Which steps required? Of course, the best internal/external performance is got when the other screen is disabled.

Dschijn Posted September 30, 2014 Share Posted September 30, 2014 To instal the eGPU I just followed exactly your guide: http://forum.techinferno.com/diy-e-gpu-projects/7580-%5Bguide%5D-2014-15-macbook-pro-iris-gtx780%4016gbps-tb2-akitio-thunder2-win8-1-a.htmlFor Optimus I booted without any display connected. Optimus with a connected external (but not used) external display doesn't make that much sense to me (no offense)! Quote Link to comment Share on other sites More sharing options...
euqlaog Posted September 30, 2014 Share Posted September 30, 2014 Ok thanks! I need sometimes both the screens just for more space. When gaming, the sharp retina screen is my favourite over 1080p external Quote Link to comment Share on other sites More sharing options...
Dschijn Posted September 30, 2014 Share Posted September 30, 2014 Gaming on the Retina display is something that I need to test in the next days.

aqqua Posted September 30, 2014 Share Posted September 30, 2014 @goalque thank you for detailed instructions I will try them out when I am at home @Dschijnthank you for tying out optimus. It gives hope that it works. I especially need optimus as I dont have external monitor and rather don't want to buy one. I just borrowed a monitor from a friend to test after failed to lunch akitio at the begining. Quote Link to comment Share on other sites More sharing options...
aqqua Posted October 1, 2014 Share Posted October 1, 2014 @goalqueI tried the instructions exactly but the same result happens. I checked both devices if there is hardware problem. Gpu is working with pe4l and akitio is on system info on mac osx. So I guess both devices are working. Till yesterday akitio was working with external screen. One problem accured after I deleted nvidia drivers with drive sweeper and now egpu with akitio doesnt work also not on external screen. One point is that egpu with pe4l works fine but this time somehow wireless card in device manager doesnt work and no internet. Without thunderbolt, wireless card works again after reboot. I installed windows again in efi but no change. I assume there is some kind of problem occured in mac after I used driwe sweeper. It would be great if anyone has an idea about it.- - - Updated - - -I forgot to mention. I got the 16x pci riser with molex and tried it without an adaptor but no change.

Dschijn Posted October 1, 2014 Share Posted October 1, 2014 Did you:- power the riser (connected the molex to the ATX PSU)- disconneted the AKiTiO PSU- did the "trick" on the 20/24-pin PSU connector to get it started?- connected all 6-pin and 8-pin connectors to the GPU- powered the eGPU setup before anything else- conncted TB cable- last: started the PC/Laptop Quote Link to comment Share on other sites More sharing options...

Admittedly, their US$270 pricepoint still makes it a bargain standout when you consider it has a better feature set than it's nearest price competitors. Those being the US$199 Firmtek (TB1) and US$314 Sonnet SEL (TB2).

aqqua Posted October 2, 2014 Share Posted October 2, 2014 Thanks guys for all your help by trying optimus for me and for valuable suggestions. I made a clean install of windows and tried akitio further for optimus. the results are good now I have optimus. I needed a different sequence to make it work by comparing it with pe4l v.2.1 So what I did is, Pulled out the cable (yellow black) connecting akitio thunderbolt board and akito 16x board. (thunderbolt cable plugged in) Started mac with alt and waited in boot options. Started akitio with powered riser. (no akitio adapter) When waiting in boot options I plugged the cable (yellow black cable on the akitio board) and boot in windows. And it worked finally. So in my case it worked only with that method. Can it be besause of the graphichs card I am using? It is gigabyte gtx660. Quote Link to comment Share on other sites More sharing options...
